You are driving down the highway on your way back from a business trip. You went with one of your coworkers but returned without them because they found another ride back. When the sun was out you were seeing nothing but trees and occasionally other cars. It's dark now and you’ve been driving for hours and haven’t seen another car for a long time. Suddenly you see a streak of red appear on the road and drag on for what seems to be about 100 feet.
Do you stop and get out to investigate?
Do you stop but stay in the car and look around for anything within sight?
Do you keep on driving and pay no mind to it?
